Cummins big cam problem HELP!!

Recommended Posts

Ok so i have a 1994 ford L9000 and it will not start... the starter is fine. The truck just won't turn all the way over. Sometimes it will start up and run for a couple hours until it randomly shuts off. The truck has 3 brand new batteries. My coolant and oil is fine. The water separator is also fine. I also just replaced my 2 oil filters yesterday. So what do you pros think? Im not very experienced in working on dump trucks.

                    An L9000-1994 with a big cam-It should be a N14 or L10. What color is the engine? Black or tan.

The engine is red but i believe it's an L10.

It cranks no problem. It just won't fire up except sometimes. And when it does fire it doesn't last very long.

               Well before we go any further you need to nail down what exact engine you have. Because starting in 94 the L10 became the M11 Celect tier 2 engine, the L10 was mechanical.

               There should be a data plate on the left front of engine telling you what it is.

Ok all i see is 300842 on the side of the motor. It is a cummins big cam. It has a cummins PT fuel system and i don't think the electric fuel shut off valve is wired correctly. It only has 1 post on it. Should i rewire that?
